Reach on rubber plate 10. Then, when the stock is separated from the terminal portion of the corn supply device 5, the culm is guided by the culm guides 24, 25 and reaches the starting end of the front inheriting chain 7, and the tip side hangs down. It is guided so as to slide on the existing cereal guide rubber plate 10 and falls onto the entrance funnel 6 so as to be taken over in an orderly manner. At this time, the takeover cereal is slid down onto the entrance funnel 6 at a low position in a stepped state from the end of the cereal supply device 5, so there is almost no conveyance resistance, and the state is delayed in the conventional tip. It will be supplied to the handling room.

このようにして、引継ぎ穀稈は、株元が前部受継チェン９ｂの終端部から補助受継チェン９ａの補助を受けながらフィ−ドチェン２２に受け継がれ、穂先側が、上述したように、入り口漏斗６から扱室に供給されて脱穀作用を受けながら後方に搬送されることになる。 In this way, the inherited cereal is inherited by the feed chain 22 while the stock is being assisted by the auxiliary inheritance chain 9a from the end of the front inheritance chain 9b, and the tip side is the entrance funnel 6 as described above. It is supplied to the handling room from the rear and conveyed backward while receiving the threshing action.

以上述べたように、本発明は、刈取前処理装置３の穀稈供給装置５の終端部から脱穀装置２の入り口漏斗６上に引継がれる穀稈は、高い位置から段差のある低い位置にきわめて円滑に引継がれて脱穀装置２に供給されるものとなった。 As described above, according to the present invention, the cereal that is handed over from the terminal end of the cereal supply device 5 of the pre-harvest processing device 3 to the entrance funnel 6 of the threshing device 2 is extremely different from a high position to a low position with a step. It was taken over smoothly and supplied to the threshing apparatus 2.

そして、穀稈ガイドゴムプレ−ト１０は、刈取前処理装置３の穀稈供給装置５から脱穀装置２の入り口漏斗６上に引継がれる穀稈の搬送姿勢を安定させることができて、穂揃いを良くしながら脱穀装置２に供給できるから脱穀効率を高める効果を発揮することができる。 Then, the culm guide rubber plate 10 can stabilize the conveying posture of the culm that is handed over from the cereal supply device 5 of the pre-harvest processing device 3 to the entrance funnel 6 of the threshing device 2, so Since it can supply to the threshing apparatus 2 while improving, the effect which improves threshing efficiency can be exhibited.

Another embodiment 2 relates to an open device for a waste chain provided in a waste portion of a threshing device, which can be easily cleaned and removed when the waste is clogged between the waste chain and the holding rod. is there.

まず、排藁チェン４５は、基部側を駆動スプロケット４６に係合し、先端側を従動スプロケット４７に係合して脱穀装置の排藁部に設けている。そして、駆動スプロケット４６は、図示しない扱胴回転軸の終端部から回転動力が伝動される入力プ−リ４８に伝動機構４９を介して伝動可能に構成している。そして、伝動機構４９は、駆動スプロケット４６と入力プ−リ４８と共に伝動ケ−ス５０に軸受支持した構成としている。そして、他方側の従動スプロケット４７は、テンション作用ができるように軸受して構成している。そして、排藁チェン４５は、回動支点軸５１に回動自由に支持した支持ア−ム５２を先端側に連結して固着しており、基部側の前記伝動ケ−ス５０の固定状態を解除すれば、上方にオ−プン回動できる構成としている。 First, the waste chain 45 is provided in the waste part of the threshing device with the base side engaged with the drive sprocket 46 and the tip side engaged with the driven sprocket 47. The drive sprocket 46 is configured to be capable of being transmitted via a transmission mechanism 49 to an input pulley 48 to which rotational power is transmitted from a terminal portion of a barrel rotation shaft (not shown). The transmission mechanism 49 is supported by the transmission case 50 together with the drive sprocket 46 and the input pulley 48. The driven sprocket 47 on the other side is configured as a bearing so that a tension action can be performed. The waste chain 45 is fixedly connected to a distal end side of a support arm 52 that is rotatably supported on a rotation fulcrum shaft 51 so that the transmission case 50 on the base side is fixed. If it is released, it can be opened upward.

すなわち、前記伝動ケ−ス５０は、図８および図１０に示すように、脱穀装置に固定して排藁チェン４５の上方に配置している上部フレ−ム５３に、取付板５４と、連結部材５５と、固定ボルト５６とを介して係脱自由に連結支持した構成としている。具体的には、図１０に示すように、上部フレ−ム５３の取付板５４に、伝動ケ−ス５０側の連結部材５５を重ねて固定ボルト５６によって固着する構成としている。 That is, as shown in FIGS. 8 and 10, the transmission case 50 is connected to the upper frame 53 that is fixed to the threshing device and disposed above the rejecting chain 45, and the connection plate 54. It is configured to be connected and supported so as to be freely disengaged through the member 55 and the fixing bolt 56. Specifically, as shown in FIG. 10, the connection member 55 on the transmission case 50 side is overlapped on the mounting plate 54 of the upper frame 53 and fixed by a fixing bolt 56.

このように、固定ボルト５６は、取付板５４に連結部材５５を重ね合わせて、その上側からねじ部を差し込んで、ハンドル５７によって回してねじ止めする構成としている。
つぎに、排藁チェン４５は、オ−プンするときには、ハンドル５７によって取り付け時の逆に回して固定ボルト５６を外し、取付板５４から連結部材５５を分離して上方に回動することができる。 As described above, the fixing bolt 56 is configured such that the connecting member 55 is overlapped on the mounting plate 54, the screw portion is inserted from the upper side thereof, and is turned by the handle 57 to be screwed.
Next, when the waste chain 45 is opened, it can be rotated by the handle 57 in the reverse direction at the time of attachment to remove the fixing bolt 56 to separate the connecting member 55 from the attachment plate 54 and rotate upward. .

そして、排藁チェン４５は、下側に沿わせて挟持杆５８を設け、排藁を挟持しは搬送する構成とし、穂先側には、穂先排藁ラグ５９を併設して構成している。
別実施例２は、上述のように、排藁チェン４５を単独でオ−プン可能に構成しているから、挟持杆５８との間に藁詰りが発生すると、固定ボルト５６を外して比較的簡単に上方に回動して詰っている藁の取り除きができる利点がある。 The waste chain 45 is provided with a holding rod 58 along the lower side to sandwich and transport the waste, and a tip waste lug 59 is provided on the tip side.
In the second embodiment, as described above, the evacuation chain 45 is configured to be openable alone. Therefore, when clogging occurs between the holding rod 58 and the fixing bolt 56, the fixing bolt 56 is removed. There is an advantage that the clogging can be easily removed by rotating upward.

別実施例３
つぎに、図１１乃至図１４に基づいて別実施例３を説明する。
別実施例３は、揺動選別棚６０の終端部の外側に設けた排塵ガイド６１に関し、排塵物の排出作用を促進しながら圃場の既刈稈側に誘導落下するものである。 Example 3
Next, another embodiment 3 will be described with reference to FIGS.
The third embodiment relates to the dust removal guide 61 provided on the outer side of the end of the swing sorting shelf 60 so as to be guided and dropped to the already cut shear side of the farm field while promoting the discharge action of the dust.

まず、コンバインに搭載された脱穀装置６２であって、揺動選別棚６０は、図１１に示すように、脱穀装置６２の選別室６３に揺動自由に支架して設けている。そして、揺動選別棚６０は、後部にストロ−ラック６４を配置して設け、終端部にはゴム垂れ６５を垂下して設け、選別しながら移送してきた排塵物を終端部から機外に排塵する構成としている。そして、排塵ガイド６１は、図１２および図１３に示すように、左右二つを揺動選別棚６０に取り付け、背面視（図１２参照）において、右側を下方にして傾斜し排塵物を圃場の既刈稈側に誘導落下する構成としている。そして、排塵ガイド６１は、後縁の下側に切欠部６１ａを設けて排藁カッタ−６６の拡散ロ−タ６７に接近した配置構成としている。 First, in the threshing device 62 mounted on the combine, the swing sorting shelf 60 is swingably supported in the sorting chamber 63 of the threshing device 62 as shown in FIG. The swing sorting shelf 60 is provided with a straw rack 64 disposed at the rear, and a rubber sag 65 is provided at the end to suspend the dust discharged from the end to the outside. It is configured to discharge dust. As shown in FIGS. 12 and 13, the dust discharge guide 61 is attached to the swing sorting shelf 60 on the left and right sides, and is tilted with the right side downward when viewed from the back (see FIG. 12). It is configured to be guided and dropped to the already-cut culvert side of the field. The dust discharge guide 61 has an arrangement configuration in which a notch 61 a is provided on the lower side of the rear edge and is close to the diffusion rotor 67 of the discharge cutter 66.

そして、排塵装置６８は、実施例の場合、排塵風を排塵ガイド６１と拡散ロ−タ６７側に排塵する構成にしている。
別実施例３は、以上のように構成しているから、コンバインによる刈取脱穀作用に伴って揺動選別棚６０の終端にあるストロ−ラック６４から外側に排塵された排塵物は、排塵ガイド６１上に落下する。すると、排塵物は、排塵ガイド６１の傾斜によって既刈稈側に案内されて落下しながら拡散ロ−タ６６に達し、圃場面に拡散される。このようにして、排塵物は、圃場の既刈稈側に落下するから次工程においてコンバインの前端部にある分草杆に引っ掛かることがない。 In the case of the embodiment, the dust exhaust device 68 is configured to exhaust the dust exhaust air toward the dust exhaust guide 61 and the diffusion rotor 67.
Since the third embodiment is configured as described above, the dust discharged to the outside from the straw rack 64 at the end of the swing sorting shelf 60 due to the harvesting and threshing action by the combine is discharged. It falls on the dust guide 61. Then, the dust discharge material is guided to the already-cut culvert side by the inclination of the dust discharge guide 61, reaches the diffusion rotor 66 while falling, and is diffused in the field. In this way, since the dust is dropped to the already-cut culvert side of the field, it is not caught by the weed culvert at the front end of the combine in the next step.

そして、実施例の場合、拡散ロ−タ６７は、上側の排藁カッタ−６６で切断した藁と、排塵装置６８から排塵された排塵物と、排塵ガイド６１上からの排塵物とを受け継いで圃場面に拡散する。 In the case of the embodiment, the diffusion rotor 67 includes the soot cut by the upper exhaust cutter 66, the dust exhausted from the dust exhaust device 68, and the dust exhaust from the dust guide 61. It inherits and spreads in the field.

このように、別実施例３は、揺動選別棚６０の棚先から排出される排塵物を圃場の既刈稈側に迅速に排塵して詰りや停滞を起こさせない特徴を有する。 As described above, the third embodiment has a feature that dust discharged from the shelf tip of the swing sorting shelf 60 is quickly discharged to the already-cut culvert side of the field and does not cause clogging or stagnation.
